DUMPING-WAGON.

Specification of Letters Patent.

Patented Apr. 11, 1916.

To all whom it may concern:

Be it known that I, ULYssns G. SHULTZ, a citizen 4of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Dumping Wagons, of which the following is a specication. p

This invention relates to improvements in dumping wagons of the character usually employed in delivering coal, .and the object in the present invention is to provide a wagon in which the body may be elevated from the frame in such manner as to permit of dumping its contents at diierent degrees of elevation.

A vfurther object is to provide a wagon in which the frame may be placed in comparatively close proximity to the axles, and in which the elevating arms by which the body is lifted, will, when the body is in lowered position, lie within the confines of the wagon frame, in contradistinction to those in which the lower extremities of the elevating arms depend below the axles and in close proximity to the ground, when the body is so lowered.

f By means of this construction, any tendency to top heaviness is overcome, while at the same time I am enabled to attain sufficient height of body, when elevated, to deliver the wagons contents in all ordinary circumstances.

lThe invention comprises a pair of main elevating arms by means of which the front end of the wagon body may be raised from the frame, and a pair of secondary elevating .arms by means of which the rear end of the body may be raised and the arrangement is such that the main arms may be operated independently of the secondary arms, so that the front only of the body will be raised, or they may be operated jointly, front is raised or after the front has .attained a desired height.

The invention is more fully described in the following specification and clearly illustrated :in the accompanying drawings, in which Figure 1 is a side elevation of my wagon, with 'the body at full elevation, the frame and a portion of the body being shown in central section. Fig. 2 is a detail, showing in gears and the lends of the winding shafts. Fig. 3 lis a side elevation of wagon with the body in lowered position, but showing, in dotted lines, the body with the front end in partially raised position.

The numeral 1 designates the wagon frame and 2 the body, both of which are of ordinary construction. f

The numeral 3 designates the main elevating arms, which are pivotally attached to the frame near the rear end thereof, and whose opposite ends are pivotally attached to the body near the forward end. These two pivotal connections form the only permanent connections between the body and the frame. These arms are each provided with an elevating` bar 4l, one end of which is pivotally attached to the armB at a point slightly forward of the central point between its pivoted ends, and the other ends of these bars 4: are each provided with a flanged roller 5.

The numeral 6 designates a track on which the rollers travel. These tracks are inclined upwardly from the ,forward end of the frame to a crossbar 7 about midway of the length of the body, and from that point, they incline downwardly toward the rear of the frame and depend slightly below the lower edge of the frame and terminate in a curved portion 8.

The rollers 5 are further provided with guides 9, between which and the tracks they travel and are prevented from jumping, and the rear ends of these guides form stops 10, to limit the travel of the rollers when the body is elevated.

The rollers 5 are mounted 4on a rod 11 and a winding chain or cord 12 is attached at one of its ends to this rod, while the opposite end is attached to and `adapted to be wound on a winding shaft 13. This shaft 13 is mounted in a pair of hangers 14 on the under side of the frame, and is provided with a gear wheel 15 at one end, and also with a winding crank 16. It is therefore evidentthat turning the shaft 13 will draw the rollers 5 up the inclined track, and raise the forward end of the body 2, through the medium of the bars 4c and the main elevating arms.

@The numeral 17 designates a pair of secondary elevating arms, adapted to raisethe rear end of the body. These arms are pivotally attached to the frame 1, at approxi- `mately .the center of its length, and their loo .opposite o-r free ends each carry a flanged roller 18, mounted on .a rod 19, and adapted to bear against and ride'on tracks 20 attached to the under side of the body at the rear end thereof. Each of these arms 17 is provided with an elevating bar 21, one end of which is pivotally attached to the arm at a point approximately midway of its length while the other end is provided with a flanged roller 22, mounted on a shaft 23 and adapted to ride on the rear or downwardly inclined portion of the track 6.

A winding chain or cord 24E is attached at one of its ends to the shaft 23, and its opposite end is attached to and adapted to be wound on a winding shaft 25 which is also mounted in the hangers 14, parallel with the winding shaft 13, and it is provided with a gear wheel 26 adapted to mesh with the gear 15. It is also evident that when this second winding shaft is rotated, the rollers 22 will be drawn up the inclined tracks 6, and, through the medium of the bar 21 and the arm 17, the rear end of the body 2 will be raised.

In Fig. 2 I have shown the gears 15 and 26 in mesh, and when they are in this position, and the crank 16 is operated, it is evident that both winding shafts will turn, and that both the main and secondary arms will be raised, thus lifting the body at both front and rear. When, however, it is desired to raise the front of the body only, the shaft 13, carrying the gear 15, is pulled out, until the gears no longer mesh, as shown in dotted lines in the said Fig. 2, and the turning of the crank 16 will then rotate only the forward shaft 13, and this action may be continued until the front 0f the body has attained the desired height, when the shaft 13 may be pushed into its former position, with the gears in mesh, and the continued turning of the crank will cause both winding shafts to operate in unison and raise both ends of the body.

The winding shaft 13 is provided with a stop collar 27, adapted to contact with the hanger 141 when the shaft is pulled out, and thus limit its movement in this direction.

It will be noted that the only permanent connection between the frame and the body is the main elevating arms at the forward end of the body. The rear end of the body merely rests on and rides the rollers 18, so that all strain between the main and secondary'elevating arms is eliminated.

When the body 2 is in lowered position, as shown in Fig. 3, full lines, the entire elevating mechanism rests entirely within the confines of the frame and the bed of the body portion, so that the wagon may be carried on extremely low axles, overcoming the tendency to lean while on a sloping road, and further overcoming the tendency of bending or otherwise injuring the elevating arms as is the case where they depend below the axles. A

Having thus described my invention, I claim 1. In a wagon of the character described, a frame, a body portion, a pair of main elevating arms pivotally attached to the rear end of the frame and to the forward end of the body and forming the only permanent connection between the two, a pair of secondary elevating arms pivotally attached to the frame and having rollers at their free ends in contact with the rear end of the body, a pair of winding shafts, gears on said shafts adapted to be placed into or out of mesh with each other by shifting one of said shafts lengthwise, a pair of elevating bars pvotally attached to each of the pairs of elevating arms, rollers carried by the free ends of said bars, a track for the rollers and flexible connections between the winding shafts and said rollers, whereby either one or both of said winding shafts may be turned.

2. A dumping wagon comprising a frame, a body, main elevating arms attached permanently to the frame and the body, secondary elevating arms permanently attached to the frame and having only contacting connection with thebody, elevating bars pivotally attached to both the main and secondary arms, rollers carried on the free ends of said bars, inclined tracks on which the rollers move toward the center of the frame, winding shafts having independent connection with the rollers on the elevating bars of the main elevating arms and with those on the elevating bars of the secondary elevating arms, and means including a pair of gears whereby the main arms may be raised either independently of or in conjunction with the secondary arms.

3. A dumping wagon comprising a frame, a body, arms attached to the frame and body for elevating the forward end of the body, arms attached to the frame and bearing against the body for raising the rear end of the body, elevating bars pivotally attached to both sets of arms, winding shafts having flexible connection with both sets of elevating bars, gears on the ends of said shafts, one of said shafts being longitudinally slidable to bring said gears into or out of mesh with each other, hangers for said winding shafts, a stop on the slidable shaft adapted to contact with one of the hangers to limit the longitudinal movement of said shaft, and a crank on said slidable shaft for rotating either one or both of said shafts when the said gears are out of or in mesh.

4. The combination in a dumping wagon of a frame provided with main and sec-1 ondary elevating arms, elevating bars attached to each of said arms, rollers carried on the free ends of the bars, tracks for the rollers, chains attached to the rollers, independent winding shafts for said chains, gears carried by said shafts, means for throwing said gears into or out of mesh with each other whereby either one or both of said shafts may be rotated, with a wagon body having permanent pivotal connection at its forward end with the said main elevating arms and only contacting connection with the secondary arms.

5. In a dumping wagon of the character described, a body, a frame, a pair of main elevating arms, a pair of secondary elevating arms, elevating bars pivotally attached to the main arms and elevating bars pivotally attached to the secondary arms, said bars havingy rollers adapted to travel on the frame, means for raising either the main elevating arms only, or both the main and secondary arms in unison, said main arms, secondary arms and elevating bars being foldable within the coniines of the frame, when the body is in lowered position.

In testimony whereof I affix my signature.
